To al 'whom it-nary conce/rn:

Be it known that I, ALVAH L. BINGHAM,

a citizen of the Unitedl States, residing at- Muncie, in the county` of Delaware end 5 State of Indiana, havek invented a new and useful (llass-'Working Machine, of whic the following is aspecification. A

The object of my invention is'to produce a semi-automatic machine for receivlngr and forming successive charges of molten glass, the construction being such that' unskilled labor may be1 ntilizedin. its manipulation, the sev-'eral parts being,v to that end, so conveniently arrangedr with relation to each other thatno great skill is required in man-' ually assisting the mechanism to produce a marketable piece. l While. the mechanism has been especially designed for the production of so-called narrow neck" ware. it will, of course, bev understood that it is not limited to such use. 4

The accompanying drawings illustrate my invention.

In the drawings, 20 indicates'a transportable carriage upon which the entire merl'ranismV is supported so that it maybe easily transported from one furnace to anv other'and adjust-ed into glass-receiving positionV vwith upon the carriage 2() is a central Standard 21 through which a vertically reciprocable rod 22 is projected. Journaled upon the 'standard 21, and supported upon a bear-A ing 23 arranged upon a horizontal shouldergof the standard 21, is a rotatable moldcarrying structure which' comprises funda- `lnentally a horizontal blank-mold table 24, a smaller liorizontal blow -mold table 25 and aspacing collar 26 united together so' as to .rotate about. the standard 21 as a' unit.

Extending' between the two tables near" relation thereto. Mounted the edge of table. 2:45, are several verticall pivot 4pins 27 which are circumferentially spaced and which may be readily withdrawn. In the machine illustrating the present drawings, there are five of these pivot pins andl each pin forms a lsupport- -for a'blank-mold A. This blank-moldmay `lie of anyl desired form and the details of (amstruction may, ofv course, be varied to a considerable extent Without departing from the.' spirit of my invention. The` blankmold shown in the drawings comprises a pair of mating members 31, 31 hinged upon la sleeve 32 which vreceives pin 27. The

two" blank mold members 31 are provided.

with-mating mold cavities upon their ad jacent faces and at their lower ends are adaptedto fitover a base plate 33 whichis mounted upon the table 24. Each mold member'l is provided withan ear 341:01,

which is pivoted one end of a'spring operatinglink 35 of Va. form Wellknonm in glass-working machines The opposite ends of' the links 35 are pivotally connected t0 a. cross head slidably mountedv upon a radially projecting pin 37, see Fig. 9,- the several pins 37 being carried by the spacing collar of the mold table structure.

The. lilank mold sections 3.1., 31 are intermittently s ung upon their pivots at proper times radial :ornement of the appropri` are cross heed and in my present machine i have found it desirable to accom plish the opening movement of the blank mold very quickly ai a time when the mold -:ilrle is stationary, because the glass blank, in the present machine, is formed in an inverted position and, in order that the blank may not besoinsdistorted, it'is desirable that it be supported hy the blank mold as long as possible and that, when released, the condition ofthe adjacent portions of the machine shall lie such that the operative may easilyind quickly manimllyv transfer the lil-nh from its inverted position to a depending position adjacent the appropriate blow mold. .ln order to accomplish this desired result, each cross heed 36 is moved `radially by means of a pivoied lever 38 carried uportlcfblankgnold table 24 and pro- "gecting through a peritel-asino 39 therein. The upper and of each lever 3S isprovrgled with a roller l1 taking within a recess in the adjacent cross'head 36; and at the lower end is provided with a roller i3 fitted within the rui'mav of cam 44. This ruuwav comprises n small-radius portion 45 which conccntric with the axis of table l Vith large-radius portion 46 which is concentric with the :axis of table 24; and with a portion 4i which conne-cts the portions: s6 end The adjacent and unconnected ends of the portions 45 and 46 are radially spaced from each other by an amount equal io the total throw of the cam and this amount is equal to the required movement of roller 43 around the pivot of lever 38 to produce the required opening movement of cross head 36. This opening movement of cross head 3G is desired at e lime when the table structure is stationary and, therefore, in order to accomplish this movement, the 44, between portions 45 and 46 of the cam, is provided Witharedial guide in which is mounted a radiall); movable block 49 provided at its inner end with an axially extending shoulder 51 of suilicienJ angular extent to bridge the angular distance between the runways 45 and 46 so that, when any roller 43 is' brought, by the rotation of the-table structure from the runway into a position opposite the shoulder 5f (as indicatedv at the position D, Fig. 4l the block `lflnxay be shifted radially outwardly in guide 48 so as Ato bring the'lshouicler lfnto circumferentinl aline-ment with the innerwali of the runway portion, 46. Block 49 is provided on under side with a downwardly projecting pin which takes int-o u slot 53 .formcd in onel arm of a lever 54 pivoted at 5:5 upon a bra'lcket 56 holted to standard 21. 'Ille opposition end of lever 54 is provided with a pin see' Fig. i3, which vlies within the slot of e ,cam :38 :carried b v the main drive shaft- 59l- Shaft- 5!) is driven in any suitable Way, as, for instance, by a worm Wheel 6l enga "ng a uorm (i2 carried liv a shaft- 63 provi e( writh a clutclififl engaging a gear 65 driven h ha pinion 66 carried by a motor 67. y
